Uninitialized constant ActionView::Helpers::AssetTagHelper

Rails
1

Hi All,

I just wiped out my hard drive, did a fresh install of os x 10.5, and
upgraded to rails 2.3.2. i installed the mysql pkg for os x, and
created the databases i needed for the project i was working on before
the upgrade.

However when i run rake db:migrate to run my migrations i get this
error

uninitialized constant ActionView::Helpers::AssetTagHelper

I’ve found some stuff about the AssetTagHelper, but i haven’t found
anything related to this error when running the rake db:migrate.

Does anyone have any idea what could be going on, or link me in the
right direction?

Thanks,
John

I’ve made some progress since this post. I’ve installed ruby and
rubygems from source, and now when i run rake i get this error:

Rails requires RubyGems >= 0.9.4 (you have ). Please gem update -- system and try again.

For some reason boot.rb can’t find which version of rubygems i have
installed, but i have 1.3.1 installed.

Has anyone else experienced this?

Thanks,
John

It sounds like you have two gem versions in your path. What does the
output of “gem env” give you?

I have the same problem you describe, and it has nothing to do with
rubygems, in fact the problem is related to a rails plugin called
app_config. I am still trying to patch the problem with rails 2.3.2, but
for now you can try just to uninstall that plugin.

Sorry, that was not the cause of the error, it was overriding some Date
and DateHelper methods to translate months and days.
